Tail RFID identification system - Digitail™ Tag
Digitail Tag from Somark is the world’s smallest RFID tag. It is easy to implant by even novice technicians, has a reliable read distance up to 5 cm and does not migrate or cause side-effects.
The Digitail Tag is only 6mm long, 0.5 mm wide and only 0.25 mm high. At only 0.75 mm3 in volume (16 times less than glass transponders) and requiring only a 21 gauge needle to implant, it is the least invasive of any tag in the world.
The tag comes with a pre-existing, permanent 24 character, unique ID and can be read by any compatible UHF reader, as it is ISO 18000-6c compliant. Every tag is coated in Parylene C so it is completely bio-inert and is ideal for use with any strain of mouse or rat, including immune-deficient or compromised strains.
Adventages of Somark Digitail identification tags for mice
Somark Digitail Tags are unique. They are smaller in dimension and volume than any other alternative RFID tag. They are designed to be injected into the tail rather than the body, which avoids the need to shave fur before implantation and makes the implant method much easier to learn and apply consistently. The implant location also means you can be sure where the tag is and it will never migrate. Refined Injection techniques means no would closure is necessary to prevent tag loss too.
No anesthesia is required before implanting a Digitail Tag.
Digitail has numerous IACUC / Ethics approvals as an ID method based on a simple subcutaneous injection, less invasive than Intraperitoneal injection of other transponders.
Somark tags do not contain any ferrite core or ferrous content – so they are completely compatible with any MRI or other imaging system. Also, as the tag is in the tail, you can be confident that the tag will not interfere with any cell implant sites or any other area of research interest in the head or torso.
How work Digitail identification tags for mice
Simply attach one of the pre-loaded, sterilised needle cartridges (which contain the tag in the needle) to the re-usable injector, remove the protective needle guard and then insert the needle into the tail tissue about 10 mm from the base of the tail.
Once the needle is inserted up to the 9 mm mark on the needle, press the injector button and the needle will retract, leaving the tag in place and ready to read immediately. The small gauge needle and injection location produce a self sealing entry point which means no wound closure is necessary. Watch the video.
